New submission from Ethan Furman: --> s = [] --> s += 1 Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: 'int' object is not iterable
For comparison, when NotImplemented is appropriately returned the message looks like this: --> s -= 1 Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: unsupported operand type(s) for -=: 'list' and 'int' Which is certainly more helpful than "<blank> object is not iterable" ---------- messages: 230396 nosy: ethan.furman priority: normal severity: normal status: open title: list's in-place add doesn't return NotImplemented when appropriate type: behavior versions: Python 3.5 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue22778> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
